In the present work, we report a facile approach to fabricate porous long-chain polyamides (LCPAs) through a non-conventional evaporation induced phase separation. Taking advantage of their amphiphilic nature, LCPAs can be dissolved by a mixture of a polar and a non-polar solvent. The sequential evaporation of solvents leads to the rapid formation of homogeneous pores within 1 minute. Also, it demonstrates that this approach can be applied to other long-chain polycondensates. Our finding provides a new insight to the rapid and coagulating-bath-free fabrication of porous materials.
